Description
Product Overview
The Heschen LJC30A3-H-Z/BX is a high‑performance capacitive proximity sensor designed for demanding industrial applications. Featuring a non‑shielded construction, this sensor provides a stable detection field that can reliably sense any dielectric material within a configurable range of 1‑15 mm. Its robust housing, measured at 3.98 × 2.60 × 1.61 inches and weighing only 4.59 oz, is engineered to withstand harsh environments, including exposure to dust, moisture, and temperature fluctuations common on factory floors. The sensor operates on a wide voltage window of 10‑30 VDC, delivering a consistent 200 mA NPN normally‑open (NO) output that integrates seamlessly with standard programmable logic controllers (PLCs) and other automation equipment. With a mounting hole diameter of 30 mm, installation is straightforward, allowing for quick retrofits or new builds in a variety of machinery setups. The device is certified as a non‑discontinued product, ensuring ongoing support and availability for long‑term projects.

Usage
Designed for versatility, the LJC30A3-H-Z/BX excels in a range of industrial scenarios. In material handling systems, it can detect the presence of plastic, glass, or composite components moving along conveyor belts, triggering actuators or alarms to prevent jams and improve throughput. Packaging lines benefit from its precise short‑range detection, enabling accurate positioning of containers before sealing or labeling operations. CNC machines and robotic arms use the sensor to verify tool presence or workpiece alignment, reducing cycle times and enhancing safety by preventing collisions. The sensor’s ability to sense any dielectric material makes it suitable for applications such as level detection in silos, presence monitoring in injection molding molds, and even quality control stations where non‑metallic parts must be identified without physical contact. Its wide voltage tolerance allows it to be powered from existing 24 VDC or 12 VDC supplies, simplifying wiring and reducing the need for additional power conversion equipment.

FAQ
What types of materials can the sensor detect?
The sensor is designed to detect any dielectric (non‑conductive) material, including plastics, glass, wood, and composite substances. It does not respond to metallic objects, making it ideal for applications where metal detection is not required.
Can the detection distance be adjusted?
Yes, the detection distance is adjustable within a range of 0‑18 mm, allowing users to fine‑tune the sensor for specific application requirements. The factory‑set default range is 1‑15 mm, which covers most standard use cases.
Is the sensor compatible with standard PLCs?
Absolutely. The sensor provides a 200 mA NPN normally‑open output that is compatible with most PLC input modules, relay boards, and other control hardware commonly used in industrial automation.
What is the expected lifespan of the sensor?
When operated within the specified voltage and environmental limits, the sensor typically offers a service life of 10 years or more, backed by Heschen’s warranty and support program.
How does the non‑shielded design affect performance?
The non‑shielded construction reduces the sensor’s susceptibility to electromagnetic interference, ensuring stable operation even in environments with high‑frequency equipment or strong electric fields.
